All-on-4® Treatment Concept: A Graft-Avoiding Protocol for Full-Arch Prosthetic Rehabilitation

With Dr. Saj Jivraj

Edentulous patients as well as individuals with failing dentition who want a fixed prosthetic rehabilitation face time-consuming, uncomfortable, and costly bone grafting procedures. For patients and dental clinicians treating them, the perceived complexity of rehabilitation is perhaps one of the most difficult obstacles to overcome on the road to treatment acceptance. The All-on-4® treatment concept represents a streamlined approach to treatment with elimination of grafting and utilizing minimal armamentarium available in most surgical offices.

However, simplicity of the concept does not always lead to ease of execution or success of overall treatment. To be successful at All-on-4® one must recognize the absolute requirements that must be satisfied in all cases. During this lecture the speakers will draw on their vast experience to highlight the absolute surgical and prosthetic factors to be considered for successful treatment. The speakers will also outline modifications of the All-on-4® Treatment Concept principals in situations where traditional approach would be difficult or require excessive bone removal. criteria and Surgical techniques will be discussed in depth utilizing actual case footage.

Learning Objectives:
• Select cases for All-on-4® treatment concept
• Understand the diagnostic principals in treatment of atrophic jaws
• Become familiar with surgical and prosthetic techniques for All-on-4® treatment concept
